'ELEVATO RAND WEIGHING ATTACHMENT FOR THRASHERS.

SPECIFICATION forming part of Letters Patent No. 377,358, dated January31, 1888.

Application filed May 17, 1887.

T aZZ whom it may concern:

Be it known that I, CHARLES J. HARTLEY, of the city of Decatur, countyof Macon, and Stateof Illinois, have invented certain new and usefulImprovements in Grain Elevating and Weighing Attachments for Thrashing-Machines, of which the following is a specification.

My invention relates, first, to the weighing mechanism; second, to meansfor adjustably connecting the elevator with the thrasher;

third, to a hingejoint in the elevator; fourth,

- V111 the drawings accompanying and forming a part of thisspecification, Figurel is an 'elevationof my machine from an end of thethrasher, the relative position of said thrasher being indicated bybroken lines. Fig. 2 is a side elevation of a chute. and a portion ofthe conveyer. Fig. 3 is a side elevation of a section of the elevatorembodying the hinge-j oint. Fig. 4 shows the upper portion of theelevator swung on the hinge to occupy a horizontal position. Fig. 5 is avertical section of the mechanism shown in Fig. 4. Fig. 6 is an innerface view of one side of the hinge. Fig. 7 indicates the generalconstruction of the bucket-chain used in connection with my invention.Fig. 8 is a side view of the weighing mechanism as seen from across thethrasher. Fig. 9 is a diagram of the mechanism used to adjustablyconnect the elevator with the thrasher. Fig. 10 is a detail drawing of amovable bearing for the lower shaft of the elevator. Fig. 11 is a viewof that portion of the elevator shown in Fig. 3, from the right-handsideof said figure. Fig. 12 is a central longitudinal section of a setof hinge-plates. Fig. 13 is a central vertical section of the supportfor the swinging chute.

The vertical elevator 1 is secured to the thrasher by means of rods 45,which are longitudinally adjustable in sockets 49 on the Serial No.238,-l9l. (No model.)

thrasher and in annular brackets 46 on the elevator. The sockets aresecured to the thrasher by means of flanges 51, which may be perforatedto admit screws or other securing devices. The annular brackets areintegral with clamp-plates 13, and said plates are firmly secured to theelevator by bolts 48. Set-bolts 50in the sockets and 47 in the bracketsprovide means for securing the rods (0 in any desired position ofadjustment. Securing devices, as above described, are placed one at thetop of the thrasher and one near the bottom of the elevator, and bytheir use the elevator may be readily placed and re- 6 tained in avertical position or parallel with the side of the thrasher.

At a point slightly above the top of the thrasher the elevator isprovided with a hingejoint, and. said hinge is composed of two sets ofplates on opposite sides of the elevator-casing. The sets arehorizontally coincident in all their parts, and are identical in theconstruction, with the exception of the variation that is necessary toenable them to be used in 7 5 opposite positions. Each set comprises aplate, 32, which is secured to the upper portion of the elevator, and aplate, 34, which is secured to the lower portion of the same. The platesare in the same vertical plane, with the exception of the overlappingledge 38 and square portion 33 on plate 32, the inner surfaces of whichare in approximately the same plane with the outer surface of theplates. The

lower plate, 34, is perforated to form a bearing for shaft 37, and hasan outwardly-proj ecting boss, 36, that forms a pivot for the largerperforated boss, 35, of the upper plate. On the inner side of each lowerplate, arranged diagonally above and below the pivot in line with thebucket-chain of the elevator, are projections 43 and 4.4, that sustainthe chain in the manner indicated in Fig. 5 when the upper part of theelevator is laid down, and prevent disadj ustment of both chain andbuckets.

The flange 38 and the lower portion of square 33 overlap the lower platewhen the elevator is erect, forming a substantial close joint, and whenthe upper portion of the elevator is laid down the square 33 fits overthe corner of the :00

lower plate and terminates the motion of the said upper portion when aright angle has been formed. The door 39 is hinged at 40, and is swungoutward from below to permit the top of the elevator to be laid down.

The brace-rod 19 (shown in Fig. 1) holds the top of the elevator in anupright position, and it is assisted somewhat in the discharge of itsfunction by the coincidence of the outer or back portion of thehinge-plates, which prevent motion away from the thrasher.

Grain carried up the elevator is discharged through chute 2 and hopper 3and falls in one of the quadrantal compartments of the circularmeter-frame 56, which is held against rtation by the scalebeam 59, whichpresses against the under side of the rectangular frame 58, which issecurely attached to a face of the meter. Then a quantity of grainsufficient to overbalance weight 63 has accumulated in a compartment,the meter-frame will describe a quarter-revolution, discharging thegrain and bringing another compartment in position to repeat theoperation. The novel feature of this part of my invention comprises theperipheral segment 4, which incases the compartments as they fill andwhich is pivotally connected with the shaft of the meter-frame by radialbars 61. From the under side of the lower bar extends arm 62, which isprovided with a roller that rests on an inclined projection orconformation, 60, of the scalebeam and that is substantially coincidentwith the corner of the rectangular frame that-is in position to depressthe scale-beam. WVhile a compartment is filling the casing is held inits shown position by the pressure of the scale-beam against arm 62. Asthe compartment rotates, the beam descends and removes the obstructionto the rotation of the casing, which moves with the said compartmentuntil suflicient momentum is developed to readily overcome thefrictional pressure of the grain against the casing, when the end 64-strikes the hopper 5 at 65 and abruptly terminates the motion, so far asthe casing is concerned, until the returning scale-beam pressesprojection 60 against arm 62 and returns the casing to the positionshown.

The partitions of the meter are indicated by dotted lines at 57. 66 is abracket-bearing for the scale-beam. 6 is an inclined chute that isprovided with valve 28. (Shown by dotted lines in Fig. 2.) This valvedetermines byits adjustment whether the grain shall be carried throughconveyer 7 or be discharged directly from the chute; or, in other words,it determines from which side of the thrasher the grain shall bedischarged. Grain is carried through the conveyer by scrapers on belt31,

which is driven by pulley 30. The handle 27 of valve 28 has someelasticity, and a rack,29, has recesses in which said handle presses ateither termination of its throw with sufficient firmness to maintain apractical degree of ii gidity in the adjustment of the valve.

Chute 10 is placed under valve 28, and chute 18 is placed at theopposite end of the conveyer. These chutes are identical inconstruction, and are each adjustably connected with the conveyer bymeans of pivoting'links 20 and revolving bands 24.

At each end of the conveyer is an annular band, 23, provided with aflange at its lower outer edge, on which band 24c rests and rotates. Adownward extension, 26, of the rear portion of the band partly ineascsthe upper end of the chute and provides points of attachment for thelinks. At the rear of the band is a vertical ratchet-bar, 21, and on theunder surface of the upper end of the chute is a pawlplate, 22, thatengages the teeth of the ratchetbar.

To adjust the chute horizontally, it is only necessary to swing itaround on its vertical pivot. To adjust itjvertically, force must beexerted in the direction of its length until the pawl becomes disengagedfrom the ratchetbar,when the outer end may be raised or lowered and thepawl be again permitted to engage the ratchet-bar at the desiredposition. The oblique position of the links causes the chutes to pressagainst the ratchet-bars in a vain endeavor to swing under their pointsof suspension, and the pressure so developed is utilized to increase thepermanency of the various positions of vertical adjustment in thechutes. The lateral projections 25 prevent an undue displacement of thelinks while adjusting the vertical position of the chutes.

The lower outer portion of the elevator is in the form of a flap,15,which is hinged at l .7 and detachably secured by catches 16 of anysuitable construction. The bearing 53 of the lower elevatorshaft ismounted on a sliding plate, 52, and has vertical motion in slot 54 offrame 14. \Vhen the bearing is in operative position, it is held by bolt55, which screws into the hole in the upper end of plate 52. Slidingbearings, as described, are placed one on each side of theelevatorcasing, and a rod at 17, extending from frame to frame below theelevator, provides a hinge for the flap. When it is necessary ordesirable to manipulate the chain or buckets in any manner or for anypurpose, the flap may be swung down to permit access and the bolts 55 bewithdrawn to produce slack in the chain.

Power is imparted to the elevator from the thrasher by means of chain11. A set of gearing suitably mounted at 12 changes the direction of themotion and conveys it to the opposite side of the elevator. A chainconnects gearing 12 with the shaft 37 of the conveyer, which extendsthrough the elevator, and a third chain connects the said shaft withsprocketwheel 57 on the upper shaft of the elevator. The conveyer has abelt-tightener at 9 and the elevator has a similar contrivance at 8.

The grain may be discharged from either side of the thrasher by a simplemanipulation of the handle 27 of valve 28.

Preparatory to moving the thrasher the brace-rod is disconnected and theupper por== IIS tion of the elevator and the weighing mechanism is laidon the thrasher, as indicated by doting the resistance of the frictionof the grain until a degree of momentum sufficient to readily overcomeit has been developed, whereas, if

the casing were stationary, the resistance of the friction would opposethe initial motion of the meter, and a variation in the degree offriction would perceptibly and injuriously affect the accuracy of theoperation.

I claimas new and desire to secure by Letters -Patent- 1. Ingrainmeters, in combination,.acircularmeter comprising a series ofsectorformed compartments adapted to rotate intermittently in onedirection, and a peripheral partial casing for said meter adapted tooscillate on the shaft thereof, as and for the purpose set forth.
